All of us eat every day, but most of us don’t understand nutrition. We often make mistakes in talking about good diet.
For example, many people think that foods such as rice, bread and potatoes will make one grow fat. In fact, these foods are very good to one’s health. They are good sources of many vitamins. And in comparison with steak and beef, they contain less amount of calories.
Some people don’t like canned(罐装的) or frozen vegetables, because they think fresh vegetables cooked at home are always better. This is again wrong. In fact, whether the vegetables are good or not depends more on how they are prepared. Overcooking, for example, destroys good qualities of vegetables. Vegetables cooked in too much water can lose a large amount of vitamins.
It is widely believed extra vitamins provide more energy. But taking more than the body needs doesn’t make it function better.
It is also wrong to say that vegetables grown in poor, worn-out soil are lower in vitamins than vegetables grown in rich soil. The vitamins in our foods are in the plants themselves. They don’t come from the soil. However, the minerals(矿物质) in a plant depend on the minerals in the soil.
In short, there are many false ideas about nutrition. We need to correct them.

【推荐1】Children are more likely to prefer foods they believe to be natural to human-made options, rating them higher for tastiness, safety and desirability, a study shows.
Researchers at the Universities of Edinburgh and Yale studied the preferences of more than 374 adults and children in the United States when presented with apples and orange juice and told of their origins.
In one study, 137 children aged 6 to 10 years old were shown three apples. They were told one was grown on a farm, one was made in a lab, and another grown on a tree inside a lab. Adults took part in the same study to compare age groups. Both children and adults preferred apples they believed were grown on farms to those grown in labs, researchers found. Children were more likely to refer to freshness, being outside, or sunlight when considering why they chose the farm apple. Adults were more likely to mention naturalness.
In a second study, 85 children aged 5 to 7 years old and a group of 64 adults were shown four different kinds of orange juice—one described as squeezed on a farm, one with no information about it, one with chemicals removed and one described as having chemicals added. Researchers found that the information on the juice’s naturalness had a significant effect on its rating. The participants tended to choose the more natural option based on perceived taste, safety and desire to consume.
Dr Matti Wilks of the University of Edinburgh’s School of Philosophy, Psychology and Language Sciences said, “Overall we provide evidence that our tendency to prefer natural food is present in childhood. This research offers a first step towards understanding how these preferences are formed, including whether they are socially learned and what drives our tendency to prefer natural things.”

【推荐2】Do you know that some kinds of foods you are eating every day are harming you slowly? Maybe you have a number of these foods on your menu. Let’s see if you need to start making changes in your diet.
If you have tooth decay (蛀牙) , you should avoid sugar as much as you can to reduce a risk of diabetes, cancers, obesity, heart disease and some other diseases. There are a lot of healthier ways to satisfy you. You can enjoy a bowl of fruit instead of some sweet snacks.
Cooking oil is a necessary part of your cooking. However, it has a high fat content, which can cause cardiovascular disease, obesity, cancers and Alzheimer’s disease. It’s a good idea to choose olive oil, coconut oil or avocado (牛油果) oil.
Alcohol is high in calories, which can cause physical damage, weight gain and skin problems, not to mention the bad decisions you make when you are drunk. Therefore, if you want to damage your system, just believe marketing and drink alcohol daily. Otherwise, avoid it.
Too much carbohydrate can suddenly and greatly increase your blood glucose level, which can speed up the aging process and give you wrinkled (有皱纹的) skin. You’ll age faster and be prone to diabetes, which is a big problem.
If you eat too much salt, you may have high blood pressure which is one of the leading causes of death in the world. However, don’t be too nervous and cut out all salt as your body still needs it. Just limit the amount of salt. 3.75 grams of sodium (钠) per day is a safe amount. Anything that has above 6 grams causes a high risk of heart disease.

【推荐3】Living a healthy lifestyle lies in forming the right eating habits. Here are some of the good habits you. can develop when it comes to healthy eating.
Drink plenty of water. You must drink at least 8 glasses of water a day. You may need even more water if you are in a hot environment or if you are exercising.
Eat breakfast. Breakfast is the most important meal of the day. A recent study has shown that those who eat breakfast will consume an average of 100 calories less during the day than their colleagues who skipped breakfast. They will also be able to concentrate better.
Don’t skip lunch. If you do so, your blood sugar level will drop and your metabolism (新陈代谢) will slow down. When you get home, you are starving and eat everything you can find.
We all need to snack from time to time, but please choose your snacks carefully. In fact, it’s a good idea to eat two healthy snacks besides your three main meals. Choose healthy snacks like fruits and vegetables, low fat yogurt, cottage cheese with apple sauce, and so on.
Eat your fruit and vegetables. We should eat at least 5 servings of fruits and vegetables a day. Take a piece of fruit for a snack, add some banana and raisins to your favourite breakfast cereal, have a salad with lunch, and eat at least one vegetable at dinner each night.
Do not eat your dinner too late. Try to eat dinner at least 3 hours before you go to bed. This will give your body a chance to digest most of the food before you rest for the next 8 hours. Plan dinner for the week ahead of time and make sure you have everything you need in the house so other family members can get a head start on dinner if you have a late meeting at the office.

【推荐1】April will bring a new product — the Apple Watch — into the market. Last week, the watch was firstly introduced by Tim Cook, Apple’s CEO. The price of the watch will differ from $349 to $1,099, depending on its size, strap and whether it is a sports or regular style.
Apple engineers and designers have put in a lot of thought and hard work into creating this “small screen” on your wrist. The “sensor” on the screen not only detects your finger, but knows the difference between when you are tapping, and when you are pressing harder.
The watch also has “haptic feedback”. You can send personal messages to your friend - such as drawing a star or a special sign with your fingers, or tapping the watch, say 3 times, and your friend will receive those taps on their wrist.
Besides telling the time, the watch will use Bluetooth to connect with your iPhone and show calls or text messages that come in.
According to Tim Cook, the watch may open up a whole new area of applications that we had never thought of. Some car factories like BMW have developed an app that allows its car owners to open their cars with the watch. A Hotels’ app may allow you to open the door to your hotel room without worrying about losing the smart-card. And finally, even airlines are jumping in - passengers may be able to simply wave their wrist to check into their flight.
The biggest use of the watch, however, is as your personal fitness coach. The watch can measure your pulse (heartbeat) using a sensor at the bottom of the watch. It also has the same “accelerometer” as your iPhone, so it knows when you are moving, and also how much you are walking or running. It will remind you if you have been sitting for too long without much activity.

【推荐2】Pickled sides are Chinese people’s solution to tasteless food. Just a spoonful of sauce or pickled vegetables over rice can make a meal taste a million times better.
During busy work schedules, many young people in China don’t have the luxury of enjoying insightful conversations with friends and family at the dinner table. Instead, they find themselves eating alone.
Chinese youth are kept company during these 20-to-30-minute windows by TV shows or short videos, which they stream on their phone, tablet, or television. On the Internet, such content has been called “digital pickled vegetables”.
Some popular picks include classic Chinese dramas and situation comedies (sitcoms) like Empresses in the Palace and My Own Swordsman. American sitcoms such as Friends and How I Met Your Mother are also favored for their amusing jokes and simple story lines. You don’t need to know anything about either to get a good laugh from a random episode.
Some have questioned the value of such videos, pointing out that some explainers ruin good films and books and that no-brainer mini-series aren’t informational. On the other hand, we see nothing wrong with some harmless fun to accompany a lonely meal after a long day of work. Instead of being accompanied by friends and family during meal my young people in China are kept company by TV shows or short videos.
Can this habit affect your diet? According to a research paper published in 2019, you may eat more unconsciously. An international research team asked 62 volunteers to follow different eating patterns on four different days. The patterns included eating while looking at the mobile phone, reading magazines and without distraction (分心). After analyzing their diets, the team discovered that eating with a distraction increased intake of calories by about 15 percent.
To explore the reason, the team also invited two groups of people: one group ate while listening to a recording about another person eating and the other listened to a clip that helped them imagine themselves eating. The results showed that the second group ate less since they were more focused on their meals. When eating with the “digital pickles”, our attention can be distracted, which leads to eating more than expected.
1. Why do many Chinese young people eat alone?| A．They hate to share food with workmates. | B．They fail to have the luxury of dining space. |
| C．They tend to have busy work timetables. | D．They prefer not to talk with strangers. |

【推荐3】The surface of Mars is etched with ancient river valleys and lake basins. Some researchers think that liquid water once flowed on the Red Planet. Today, Mars is too cold for much, if any, liquid water to exist. And 3.8 billion years ago, when the flowing water formed, the sun was fainter than it is today, making it even harder to imagine a warm Martian climate. That’s why many researchers think Mars may have gone in and out of deep freezes.
Some researchers have suggested that early Mars only thawed out when large asteroid impacts or volcanic eruptions temporarily warmed the planet. But Kasting, a geologist at Penn State University, thinks warm windows from such dramatic events would have been too brief to carve the vast canyons that exist on Mars. Now, Kasting and his colleagues have come up with an alternative explanation. They think Mars may have experienced a series of climate cycles.
The idea goes like this: When Mars was cold and frozen, volcanoes continued to belch out the greenhouse gases like carbon dioxide and hydrogen into the atmosphere. There, the gas blanket trapped heat and warmed the planet up until liquid water began to flow, forming Mars’ rivers and lakes. However, warm temperatures and abundant water would also have sped up certain chemical reactions that consumed carbon dioxide, reducing the greenhouse effect and cooling the planet back down again. Then the cycle would repeat.
Kasting shared his theory with other astronomers at the December meeting of the American Geophysical Union in San Francisco, and in the journal Earth and Planetary Science Letters. So far, Kasting’s team has only shown that such an explanation is possible, according to climate models. But the researchers say field trips could help test the idea by looking for evidence of multiple warm events, and their durations.

【推荐1】Our Teen Summer Spanish Program is two weeks of fun, educational excitement that helps students learn Spanish fast. Our Spanish summer program allows our students to learn from highly trained, certified teachers and be absorbed in the language and the culture of Costa Rica.
Features include:
* Intensive(强化的) daily Spanish classes
* Extracurricular classes in dance, cooking, music, and handiwork
* Outdoor activities including hiking, camping, rafting, and ziplining(高空滑索)
* Homestay with a local Costa Rican family
* Volunteer work in needy neighborhoods
Our Teaching Methods:
We are proud to use TPRS---Total Physical Response Storytelling---in our curriculum. This innovative method uses strange and amusing stories to teach new vocabulary, increase fluency, and get students involved by giving them the opportunity to alter the details themselves. Because of the silliness, creativity, and repetition involved, TPRS allows students to learn easily and remember information effortlessly
Memorizing vocabulary and listening to lectures on grammar are slow, inefficient ways to learn a new language. The best way to truly learn and commit new material to memory is through conversation. In our Spanish classes, students can expect to speak up to 80% of each class. By speaking in the new language freely and consistently, students can see progress faster because they are using the new grammar and vocabulary that they have learned at the same time. This helps the brain remember the new words and grammar structures for future use, making it much easier to progress.

【推荐2】Throughout history, people have been interested in knowing how languages first began, but no one knows exactly where or how this happened. However, we do know a lot about languages, the languages of today and also the languages of earlier times. There are probably about 3,000 languages in the world today. Chinese is the language with the most speakers. English, Russian and Spanish are also spoken by many millions of people. On the other hand, some languages in the world have less than one hundred speakers.
There are several important families of languages in the world. For example, most of the languages of Europe are in one large family called Indo-European. The original (最初的) language of this family was spoken about 4,500 years ago. Many of the present day languages of Europe and India are modern forms of the language of 4,500 years ago.
Languages are always changing. The English of today is very different from the English of 500 years ago. In time some even died out completely. About 1,000 years ago, English was a little-known relative of German spoken on one of the borders of Europe.
If a language has a large number of speakers or if it is very old, there may be differences in the way it is spoken in different areas. That is, the language may have several dialects. Chinese is a good example of dialect differences. Chinese has been spoken for thousands of years by many millions of speakers. The differences between the dialects of Chinese are so great that speakers of Chinese from some parts of China can’t understand speakers from other parts.

【推荐3】One day, when my family was leaving a restaurant, I heard a man's voice from a car in the car-park. After a quick look at the car, I noticed the Washington license plate (牌照) at once, so I knew they had come from far away. The young man had his head partly out of the window and spoke to me as I moved closer, "Excuse me, my wife and I are trying to find a room for the night and every place in the area seems to be filled up. Do you have any suggestions for us where we might find a room?"
Well, that didn't surprise me. After all, it was the busy time of the year for tourism. As he spoke, I noticed that his wife was pregnant (怀孕的). I told them that they should just keep searching and wished them good luck in their search. The young husband didn't say any other words and backed out of the car-park and headed off. We also got into our car and drove home.
After a short time, I couldn't get this young couple out of my mind. Here they were, traveling in a different state, tired, the wife pregnant. It was at that moment that my wife told me we needed to go back and find that couple. We went back and looked for them. We even went as far as the mountain.
